With the infamous "torture memos" back in the news, it seems worth noting that my former colleague, Amos Guiora, has a brand new book, Constitutional Limits on coercive Interrogation. I have yet to read it, but have every reason to expect it will be interesting and provocative like much of his other work. There are few working in this area that have anywhere near his real-world experience on the front lines of counter-terrorism work — something which makes his refusal to endorse the "we must win so everything is permitted" doctrine that much more significant.
